What is TDMA Cell Phone Technology?

Compare TDMA Technology Versus CDMA There are three main cellular technologies: Older Analog/FDMA, Modern TDMA, Newer CDMA TDMA is the leading digital technology in cellular phones today. Time Division Multiple Access (TDMA) is one of several technologies used in digital wireless transmissions that increases the efficiency of the network by allowing a greater number of simultaneous transmissions. Networks using TDMA assign 6 timeslots for each frequency channel. Devices using the wireless network send bursts of information that are reassembled at the receiving end. TDMA builds on FDMA (Frequency Division Multiple Access) by dividing conversations by frequency and time. Since digital compression allows voice to be sent under 10 kilobits per second (equivalent to 10 kHz), TDMA can fit three digital conversations into a FDMA/Analog channel (which is 30 kHz). By sampling a persons voice for, say 30 milliseconds, then transmitting it in 10 milliseconds; the system is able to offer 3 ...  more
